Description Part Number
• Red 7 LED warning light, 10 ft two wire cable RP-WLRBLK001
• Sealed 40 amp heavy duty relay kit L450100000
• LPE Technician’s Screwdriver L950050000
• E38/E67 ECM terminal 0334680003
Specifications:
• The Lingenfelter Performance Engineering RPM-003 RPM Controlled Switch incorporates a precision 32-bit timer to
realize microsecond precision over a very wide operating RPM range. Most common tachometer pulse frequencies are
supported with no additional components required.
• The RPM-003 can perform as a standard RPM activated switch or it can provide “Window” switch type capability,
switching at one RPM level and then switching back at a second RPM level.
• Available output types:
• Normally ON ground
• Normally OFF ground
• Normally OFF +12vdc
• All three outputs (+12v activation normally OFF, GROUND activation normally ON and OFF) can be used simultaneously.
• Current draw: 0.1 amp plus current draw of device being controlled (when active).
• Outputs rated for up to 0.75 amps each.
• The RPM switch should control a relay for higher current level applications.
• Outputs have a self protect feature and will turn OFF in case of a direct short or over current condition.
• Includes a built in tachometer pull up resistor enabled by a DIP switch inside the back cover.
• Operating voltage range: 9.0 to 18.0 volts.
• Input signal type: +12 volt DC square wave or coil negative terminal and +5 volt DC reference signal applications.
• Accepts both traditional 12 volt tachometer signals and also accepts 5 volt reference engine speed signals found on
many newer cars, trucks and motorcycles.
• Analog 0-5 volt input that can accept a Throttle Position Sensor (TPS), Clutch Pedal Position (CPP) sensor, Accelerator
Pedal Position (APP) sensor, Manifold Absolute Pressure (MAP) sensor, or most any other rising or falling 0-5 volt signals.
• RPM switch settings can be adjusted in 100 RPM increments from 400 to 19900 RPM.
• Adjustable RPM hysteresis settings of 0, 50, 100, 150, 200, 250, 300, and 350 RPM.
• Custom molded high temperature glass filled Nylon 6 enclosure.
• Fully encapsulated (potted) construction for increased durability.
• When operated in standard RPM activated switch mode, the RPM-003 can be a shift light controller. For shift lights that
draw more than 0.75 amps, a relay would need to control the light.
• Input signal impedance: 100k ohms.
• 90 day warranty (from date of purchase).
